Researchers: Monkey lip-smacking resembles human speech

Lip-smacking behavior could have an important social function among gelada monkeys.

Thore Bergman, a researcher at the University of Michigan in Ann Arbor, has discovered that monkey lip-smacking resembles human speech.

According to National Geographic, gelada monkeys reside in the high mountain meadows of Ethiopa, where they have adapted to living on steep, rocky cliffs. The 100,000 to 200,000 surviving geladas are also the last remaining species of ancient grazing primates. The rare monkeys have fatty rear ends which allow them to sit and eat grass for long periods of time.
